NEK1 gene mutations found to drive ALS in new study

Mutations in the gene NEK1, a major genetic cause of amyotrophic lateral sclerosis (ALS), may work to drive the disease by destabilizing the structure of nerve fibers and disrupting the movement of molecules inside nerve cells, according to a new study. The findings, which show for the first time how…

New Brunswick adds Albrioza for ALS to its public health plan

New Brunswick is reimbursing, through its public health insurance program, the cost of Albrioza (sodium phenylbutyrate and ursodoxicoltaurine) for eligible residents living with amyotrophic lateral sclerosis (ALS). The Canadian province is the country’s fourth to provide public coverage for the oral therapy — marketed in the U.S.

Polygenic scoring system may help to predict ALS risk

A new genetic risk score that takes hundreds of different genetic variations into account may help predict who’s most likely to develop amyotrophic lateral sclerosis (ALS). The score needs to be validated in future studies before being used in the clinic, but could be important to stratify people according…

Specific mRNA molecule may be useful as biomarker in ALS

A messenger RNA (mRNA) molecule that provides the instructions for a protein involved in glutamate signaling is not edited as efficiently in amyotrophic lateral sclerosis (ALS) patients as in people without the neurological disorder, according to a new study suggesting its potential use as an ALS biomarker. Glutamate is…

Gout medication decreases risk of ALS and other diseases: Study

Allopurinol and carvedilol, two medications respectively used to manage gout and high blood pressure, significantly reduce the chances of developing amyotrophic lateral sclerosis (ALS), Alzheimer’s, or Parkinson’s disease, a new study suggests. “These findings suggest a possible new direction for repurposing or developing medications for neuroprotection,” Brad…

Some sporadic ALS patients have mutation causing other diseases

A sizable portion of people with sporadic amyotrophic lateral sclerosis (ALS) carry a genetic mutation known to cause other neurological disorders, a new study shows. “This suggests shared risk factors among these diseases, shared mechanisms that cause nerves to die – and perhaps shared therapeutic strategies in the future,”…
